Definitions

  • the flow can be adjusted by various means such as plate closures, buffer rods or simply calibrated nozzles.
  • the mechanism according to the present invention also referred to hereinafter as replacement tray, comprises a rigid metal structure that supports the refractory plates, fixed (upper) and movable (lower), keeping them pressed against each other, even when one of the two slides on the other pushed by a new plate for the restoration of the casting hole.
  • the tray also allows the emergency closing, in an automatic or voluntary manner, of the casting line by inserting a blind steel plate in place of the lower casting plate that, by closing the hole, interrupts the flow of metal.
  • Automatic closure is due for example to various problems of the entire plant, both on the casting line (break out of the billet, mechanical breakage of the line, etc.) and upstream or downstream of the continuous casting department.
  • the most common problem in steelworks is a power outage caused by a storm or an accident. Without this possibility of closing the sprue in an emergency, the metal would continue to flow out spontaneously, but would not be conveyed into the prepared area, since all mechanical organs are blocked, creating situations of serious danger for the operators.
  • the first and second actuating means comprise respective pusher members facing the respective plates, in parallel to the rail axis.
  • said pusher members are rods of hydraulic cylinders .
  • the pusher member of the first actuating means is translatable between a retracted inactive position and an advanced pushing position of the replacement plate in the lower central seat.
  • the first empty space is formed between the first lateral seat and the pusher member when this is in the retracted inactive position.
  • these pressure bodies comprise levers hinged to the frame and acting on the refractory plate that is located in the central seat.
  • the thrust of each lever is given by at least one spring, preferably a thermodynamic spring, also called a gas spring .
  • Figures 6 and 6a show, in axial section and in plan view, a lower casting plate usable with the replacement tray according to the invention.
  • the replaceable plate 8 present in the lower central seat 80 and thus in a casting position indicated with 15 in Figure 2, is maintained in pressure against the lower surface of the upper plate 6 by means of spring-holder blocks 16, preferably four, two for each of the opposite sides of the replaceable plate 8 (preferably of square or rectangular shape, as will be described below) , parallel to the rail axis X, fixed to the lower frame 7.
  • spring-holder blocks 16 preferably four, two for each of the opposite sides of the replaceable plate 8 (preferably of square or rectangular shape, as will be described below) , parallel to the rail axis X, fixed to the lower frame 7.
  • Inside of each spring-holder block 16 is housed at least one thermodynamic spring 4, preferably two, operating in parallel.
  • Each thermodynamics spring 4 acts on an outer end of a lever 5 hinged to a respective block 16 by means of a lever pin 17. The inner end of this lever 5 pushes with a predetermined force on the lower face of the replaceable refractory plate 8.
  • the replaceable plate 8 transfers the force to the fixed upper plate 6.
  • the latter is rigidly locked to the tray 100 by means of jaws 3 openable at the end of work to facilitate disassembly from the distributor ( Figures 4 and 4a) .
  • actuators for the movement of both the replacement plate 8a and the blind plate emergency 1 allows fully controlling the movement of the plates with an automatic control program, for example integrated into the control program of the casting machine .

Abstract

L'invention concerne un plateau pour le remplacement d'une plaque de coulée réfractaire d'un récipient métallurgique qui comprend un rail de guidage (130) qui définit un siège central inférieur (80) dans laquelle est placée une plaque de coulée (8) remplaçable, un premier siège latéral (82) conçu pour recevoir dans une position d'attente une plaque de remplacement (8a), un second siège latéral (84), conçu pour recevoir une plaque d'urgence aveugle (1). Un premier moyen d'actionnement (10) est conçu pour translater la plaque de remplacement (8a) du premier siège latéral (82) au siège central inférieur (80) ; un second moyen d'actionnement (2) est conçu pour translater la plaque d'urgence aveugle (1) au moins du second siège latéral (84) au siège central inférieur (80).
